The China-nexus cyber espionage actor linked to the zero-day exploitation of security flaws in Fortinet, Ivanti, and VMware devices has been observed utilizing multiple persistence mechanisms in order to maintain unfettered access to compromised environments. "Persistence mechanisms encompassed network devices, hypervisors, and virtual machines, ensuring alternative channels remain available

A trio of bugs could allow hackers to escalate privileges and remotely execute code on virtual machines deployed across cloud environments.

Microsoft last year described the threat actor — known as UNC3944, Scattered Spider, Scatter Swine, Octo Tempest, and 0ktapus — as one of the most dangerous current adversaries.

VMware has released updates to address critical flaws impacting Cloud Foundation, vCenter Server, and vSphere ESXi that could be exploited to achieve privilege escalation and remote code execution. The list of vulnerabilities is as follows - CVE-2024-37079 & CVE-2024-37080 (CVSS scores: 9.8) - Multiple heap-overflow vulnerabilities in the implementation of the DCE/RPC protocol that could

Ubuntu Security Notice 6817-3 - Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service.

Cisco Talos is disclosing a new malware campaign called “Operation Celestial Force” running since at least 2018. It is still active today, employing the use of GravityRAT, an Android-based malware, along with a Windows-based malware loader we track as “HeavyLift.”

Ubuntu Security Notice 6816-1 - Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service.

A physically proximate attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice 6567-2 - USN-6567-1 fixed vulnerabilities QEMU. The fix for CVE-2023-2861 was too restrictive and introduced a behavior change leading to a regression in certain environments. This update fixes the problem. Gaoning Pan and Xingwei Li discovered that QEMU incorrectly handled the USB xHCI controller device. A privileged guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. Various other issues were also addressed.
